Notes 1: When the A/D converter is used, the IADD is included to IDD.
2: As for the error from the logic value in the comparator mode, when the contents of the comparator register is n, the logic value of the comparison
voltage Vref which is generated by the built-in DA converter can be obtained by the following formula.

Note: System is in the reset state when the value is the detection voltage of the voltage drop detection circuit or less.
